Muscle weighs more than fat, making retired bodybuilders nature's best paperweights. Get buff and avoid scattered utility bills with today's Groupon: for $20, you get 10 fitness classes at Elements of Exercise in Dearborn (up to a $70 value). This Groupon is only valid at the South Telegraph Road location.

Elements of Exercise’s upbeat instructors, working from the mindset that fitness should be enjoyable, motivate participants of all levels during a bevy of classes designed to boost both sweat and fun levels. Synchronize your cardiovascular chronometer to the pumping beats emanating from the cardio hip-hop class, or sculpt your earthly edifice while raising your heartbeat in the intensive Knockout class. The kettlebell class introduces limbs to weighted apparatuses designed to build lean muscle, or opt to give midsections a blast of balance and strength with a Pilates class or a Pilates-yoga fusion session, which combines core-fortifying moves with soothing pretzel imitations. Check the schedule for sessions that jive with your calendar.
